The difference, as I see it, is that LIIs and LSIs are more confident in their own understanding of a system, just like LSEs and LIEs are confident in their own knowledge. I claim to know more Socionics than you. I think it's true, but it might be false
yet I have no problem in making this claim in public, or in particular, because I am confident that at least there is a good case for it, and accusations such as Phaedrus's recent ones have no effect on me at all.
Phaedrus accused me of being "cocky". That's precisely it! Everyone looks cocky in their strong functions to those who do not have the same strong functions, just like I see Se EPs as overly abrasive.
tcaudilllg has developed his own system single-handedly. Who knows whether it relates to reality or not
Yet he has no problem in defending it here, even knowing that nobody understands it or agrees with it -- he thinks we are the ones who are stupid. He has no problem with people not understanding or agreeing with it, he has a problem with non-topic hostile comments such as niffweed's.
What I see in both Phaedrus and yourself is a sort of annoyance that I am questioning your knowledge and understanding, and especially Phaedrus sees that as emotional hostility. Do you see where I'm coming from?
